-------------------------------------
Summary: [C++][Gandiva] Use platform pointer sizes in code
generation
Key: ARROW-13426
URL: https://issues.apache.org/jira/browse/ARROW-13426
Project: Apache Arrow
Issue Type: Bug
Components: C++, C++ - Gandiva
Reporter: Pablo Sichert
Currently, the JIT code generation / function invocation in Gandiva uses
`int64` for pointer types.
This breaks especially when indexing into pointers to pointers on platforms
where the pointer size is not 64 bit wide.
To represent opaque pointers, void* (or i8* in LLVM) should be used where
suitable.
